NATO begins a two-day summit in Wales to discuss Ukraine

NATO is beginning a two-day summit in Wales that is expected to focus on the problems in eastern Ukraine and approve a plan to bolster NATO's presence along the alliance's eastern borders, AP reports.

U.S. President Barack Obama and leaders of other NATO member states are meeting at Celtic Manor in south Wales to discuss a strategy to counter Russian moves in eastern Ukraine, where pro-Russian separatists have been on the offensive against Ukrainian government forces.

NATO says the separatists are supported by the Kremlin, a charge Moscow haы repeatedly denied.

Before the summit starts, Ukrainian President Petro Poroshenko is due to brief Obama and the leaders of Britain, France, Germany, and Italy about the situation in eastern Ukraine.
